The Bourke engine, first demonstrated by inventor Russell Bourke, in 1932,
but lost in the politics of wartime manufacturing, optimizes the 90 degree
optimal torque angle for converting combustion to movement, improves fuel
efficiency over the 4-stroke engine by 300%, while (depending on design)
reducing wear, noise, vibration, as well as cutting noxious emissions to
nearly zero because of its efficient use of the fuel. Numerous contemporary
replications have demonstrated its viability. It is a technology long
overdue. Bourke may be to engines what Tesla is to radiant energy -- a
scientist who did not realize the actuation of his revolutionary technology
in his day, but whose technology may be the salvation of the 21st century
energy needs.
Apparently, the Bourke design has shortcomings, which Melvin Vaux, who
worked with Bourke, has addressed in a series of patents produced in the
1990s.
This approach to fuel economy may be more plausible than the vaporizer
technologies, which create pockets of highly explosive fumes. The Bourke
engine can easily, and perhaps even optimally, run on hydrogen (which can be
produced from water), as well as Biodiesel or other less clean but renewable
fuels such as methane from garbage.
